Decide Whether the Matrices Are Inverses of Each Other $\left[\begin{array}{rr}-5 & -1 \\ 6 & 0\end{array}\right]$

True/False

Decide whether the matrices are inverses of each other. (Check to see if their product is the identity matrix I.) $\left[\begin{array}{rr}-5 & -1 \\ 6 & 0\end{array}\right]$ and $\left[\begin{array}{cc}0 & \frac{1}{6} \\ -1 & \frac{5}{6}\end{array}\right]$
